List and describe the different types of programs that are executed on a computer.
What will be an ideal response?
There are two types of programs. The first type, applications, includes those programs designed for a specific use and with which you commonly interact, such as word processors, computer games, graphical manipulation programs, and computer system utilities. The second type, operating system (OS) software, consists of a series of software components used to control the hardware of your computer. Without an operating system, you would not be able to use your computer. Turning on a computer loads the operating system into computer hardware, which then loads and centrally controls all other application software in the background. At this point, the user (the person using the computer) is free to interact with the applications, perhaps by typing on the keyboard or clicking a mouse. Applications then take the information supplied by the user and relay it to the operating system. The operating system then uses the computer hardware to carry out the requests.
